DISAPPEARING. WINDOW.

SPECIFICATION forming part of Letters Patent No. 780,902, dated January24, 17905.

Application filed August 31, 1904. Serial No. 222,814.

To @ZZ whom, t may concern:

Be it known that I, JOHN J. MLLER, a citizen of the United States, and aresident of the city of New York, borough of Manhattan, in thecounty andState of New York, have invented. a new and Improved DisappearingWindow, of which the following is a full, clear, and exact description.

rlhis invention relates tothe construction of window casings and sashes,together with their attachments, the object of the invention being toproduce an arrangement whereby the sashes may disappear in the easementof the window orin a wall in order toincrease the area of the opening ofthe window.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and definitely set forth in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar characters of reference indi ing an attachmentconstituting a part of the invention. Fig. 5 is a horizontal sectiontaken at substantially the height of the window-sill and representing aportion of the windowcasement and the sashes. Fig. 6 is a sectionsomewhat similar to Fig. 5, but representing the sash-cords in adifferent position; and Fig. 7 is a horizontal section similar to Figs.5 and 6, but representing a modified construction of Lan attachment forretaining the sash-cords.

Referring more particularly to the parts, 1 represents a window-framethe upper portion of which may be of any common construction,4comprising guide strips 2, which comprise parting-strips 2br and beads2a, forming rims 3V therebetween, through which a pair of sashes 4 and 5may be guided in the usual manner.

These sashes are counterweighted in the usual manner, the counterweightsbeing attached by means of the usual sash-cords 6, which pass overpulleys 7 into the interior of the casement of the window, as will bereadily understood.

Below the sill 8 of the window the Casement thereof is formed intorecesses or chambers 9 and 10, which are disposed directly below theguide-runs 3, in which the sashes 4 and 5 are guided. The chambers 9 and10 are formed between solid panels 11, the said panels beingrespectively substantially in alinement with the beadsl 2, At the sidesthe chambers 9 and 1() are parted by centrally-disposed guidestrips 12,which constitute continuations of the parting-strips 2". o Y

As indicated most` clearly in Figs. 2 and 3, the gu ide-strips 2 are cutaway at substantially the level 13 in order to enable the aforesaid sill8 to slide into the position in which it is shown in Fig. 2. When inthis position, the sill "rests upon the upper edges of the panels 11.Its upper face is provided with a weatherstrip 14, which is adapted toabut against the outer f ace of the lower portion of the sash 5v whenthe sashes are disposed in their closed \relation, as indicated in Fig.2.

In order to prevent any possibility of the sash-cords 6 from interferingwith sliding the sill 8 into position, there is provided a keeper 15,which is illustrated most clearly in Fig. 4. This keeper consists of aplate which is attached to the side face of the casing at the bottom ofa recess 16, formed in the partingstrip 2b. It may be attached by meansof screws 17, as shown, and its extremities project laterally acrosselongated recesses 18, which are formed in the face of the easement atthis point. In this connection it should be understood that the recess16 is in substantial alinement with corresponding recesses 19, which areall substantially at the level 13, so as to constitute a guide for thesill when slid into position, as will be readily understood. In order toenable the keeper 15 to perform its function of retaining the sash-cords6, its extremities are formed into hooks 20, which curve slightlyinwardly toward the bottom of IOO which the sash-cords 6 are attached inthel usual manner.

In operating the window when it is desired to have the sashes 4 and 5disappear in the easement the lower sash 5 may be raised somewhat fromits lowermost position, in which it is shown in Fig. 2. After it hasbeen raised in the manner suggested the sill 8 would be slid inwardly insubstantially the position in which it is shown in Fig. 3. The sasheswould then 'be forced downwardly into the chambers 9 and l0. In forcingthe sashes downwardly in this manner the sash-cords 6 would be found tolie in front of the keeperplates 15 in the manner indicated in Fig. 5.In order to remove them from the path of the sill 8, so as to enable thesame to be returned, they may be pushed rearwardly7 into the recesses 18until they are received behind the hooks or extensions20'in the mannerindicated in Fig. 6. IVhen the sash-cords are stowed in this manner, thesill could be slid back into place, as will be readily understood. Inorder to facilitate the returnotl the sashes to their normal position,the upper edges thereof are provided with enlarged recesses 22, in whichsmall handles 23 would be conntersunk, and these handles could begrasped to draw the sashes upwardly, as will be readily understood.

In Fig. 7 is illustrated a modified arrangement for maintaining thesash-cords in the recesses 18. IVhen adopting this form of theinvention, the upper edges of the sashes are provided with grooves 24,which extend to the sides of the sashes, as shown, and aford means forguiding' plates 25, as shown. The outer edges of these plates arerecessed, as at 26, and their side edges are provided with notches 27.Springs 28, thrusting against the inner extremities of the grooves 24.-,tend to force these plates 25 outwardly. Catches 29 are provided, whichmay engage notches 2i' in order to maintain the plates 25 in a retractedposition. In Fig. 7 the plate used in connection with the sash 5 is heldin this retracted position. However, when the plates 25 are releasedfrom the catches, as indicated in connection with the sash 4i, theplates will be forced outwardly by the springs, and their outerextremities will engage the sash-cords, forcing the same rearwardly intothe recesses, as will be readily understood. It should be understoodthat the plates 25 in connection with their guides and springs are allcountersunk into the sashes, so that they oiiier no ohstruction to thesliding in of the sill.

In practice where the sill of the windowframe is located so near to theHoor that the sashes could not be housed in the space between the iioorand the sill it should be understood that the lower portion of thecasement would be extended below the llioor, so as to enable the sashesto be received within the same in the manner described.

By means of the construction illustrated and described above a verysimple arrangement is produced, enabling the sashes to disappear withinthe easing. Moving the sashes out of the frame of the window is oftendcsirable, and especially for the purpose of increasing the ventilation.Such an arrangement is also desirable sometimes where it is necessary tomore objects, such as safes, into a building through the window.

Having thus described my in yention,l claim as new and desire to secureby Letters Patent l. In a window construction, in combination, aeasement, a sill movably mounted between the inner faces of saideasement, sashes guided in said casen'ient and adapted to be depressedinto the space below said sill, sashcords supporting said sashes andnormally lying in the path of movement of said sill when said sashes aredepressed, and means for defiecting said sash-cords from their normalposition adjacent to said sill.

2. In a window construction, in combination, a easement, sashes guidedtherein, sashcords supporting said sashes, a sill adapted to slide insaid easement, said sashes being deprcssible below said sill, saideasement haring recesses adjacent to said sill, and means for deiectingsaid cash-cords into said recesses.

3. In a building construction, in combination, a easement, slidingsashes mounted therein, said easement having a recess in the lowerportion thereof into which said sashes may pass, a sliding sill,sash-cords in connection with said sashes, said easement having recessesadjacent to said sill and adapted to receive said sash-cords, and akeeper projecting laterally across said recesses and adapted to retainsaid sash-cords therein.

In testimony whereofI have signed my name to thisspecilication in thepresence of two subscribing witnesses.

JOHN J. MLLER.
